Overview
The STMPS2242MTR is a dual-channel power distribution switch produced by STMicroelectronics. This component is designed for applications where heavy capacitive loads and short-circuits are likely to occur. It features high-side MOSFET switches with a low on-resistance, making it suitable for power distribution systems that require multiple power switches in a single package.
Each switch is controlled by an independent logic enable input, and the device includes several protection mechanisms such as current limiting, thermal protection, and overcurrent logic output. This ensures reliable operation and prevents damage from overloads and short-circuits.
